Abstract: A night vision goggle (NVG) attachment device retrofit to an existing monocular or binocular type NVG system to provide additional environmental information to the user of the NVG device. The attachable device includes a ring connector having one or more external display projectors positioned on the objective side of the NVG optical system. A sensor electronics module is attached to the ring connector and houses a number of environmental sensors, including IR transmitters and receivers for range finding information, radiation detectors, and motion/heat detectors. The sensors within the electronics module provide signal information through a connector to the existing NVG electronics. The device projects informational images into the display field of view for the user. The informational displays may take the form of one or more LED indicators or LED digital numerical displays. The user may preferably activate or de-activate one or more of the environmental sensors.

Abstract: Systems and methods are provided for modifying blemished image intensifier tubes that otherwise would be inappropriate for use in strictly specified night vision equipment. The systems include masks and display elements designed and structured to be oriented in a variety of directions so as to cover over and hide blemishes within an image intensifier tube. Masks may be provided utilizing glass discs that are ground, polished, and etched with particular geometric masking elements and fixed over the display end of the image intensifier tube. Electronic components may be presented as display elements over the opaque portions of the masks. Methods for manufacturing the masks are described that detect and characterize the location and size of the blemishes and select mask type, size, and orientation for manufacture and use.
